Gear operation controller for three-wheel or four-wheel motorcycle

Abstract

The invention discloses a shift operating device of a tricycle or quadricycle motorbike, which comprises an installation holder, an operating rod, a cross shaft and a support plate, the support plate is rotatablely assembled on the installation holder through a connecting shaft, two ends of the cross shaft are respectively connected between the installation holder and the support plate through a sphere joint bearing, the operating rod is fixedly connected with the cross shaft at a position adjacent to lower end, the connecting shaft is covered with a torsion spring between the support plate and the installation holder, two stand feet of the torsion spring lean against the cross shaft, the lower end of the operating rod is connected with a pull cable or a flexible shaft that is used for forward shifting, and one end of the support plate is connected with a pull cable or a flexible shaft that is used for backward shifting. The shift operating device of the tricycle or quadricycle motorbike integrates the shifting functions of backward and forward directions into a device, all shifts can be finished by directly and manually moving the operating rod according to the design specification, reversed shift can only be realized when the operating rod is in a zero-shift position, and the structure of the shift operating device has convenient operations, fastness, safety and labor-saving effect, and is more suitable to operating habits of ordinary people.

Description

technical field [0001] The invention relates to a vehicle gear control device, especially a gear control device used on a three-wheel or four-wheel motorcycle. Background technique [0002] At present, because the power of three-wheeled and four-wheeled motorcycles is usually borrowed from the engine of two-wheeled motorcycles, there is no built-in reverse gear in the engine. A reverse gear is added to the bridge differential, and the shift control device for the forward gear and the reverse gear control device are independent of each other. For example, the reverse gear lever is set under the steering handle, and the reverse gear lever is connected to the gear through the cable. The reverse gear plate on the reverse gear is connected; the gear shifting of the forward gear then usually follows the pedal gear shifting form of the traditional two-wheeled motorcycle. This split arrangement structure makes the switch between the forward gear and the reverse gear inconvenient an...

Problems solved by technology

This split arrangement structure makes it inconvenient and quick to switch between the forward gear and the reverse gear, and also makes the arrangement of the entire gear control device on the vehicle uncompact and unsafe to operate.
